Will the planet systems be placed on a single megamap, or will they be on separate game maps, each with its own skybox?

In fact, each system is a part of the map. We still have the mega map concept, but we have a branch principle, and each solar system has its own branch. What we call the root of the universe, you really can't have players there, they're always in the star systems. In fact, they're not quite maps as such, but it's the same concept, but it's a big data-set.

So as more systems are added, it's still just the streaming system that comes into play.
